Title: Apparatus and method for header decompression
Inventor: IDO DAIJI
IPC: H04L1/00
Filed: 2001-09-10
Abstract: In a header decompression apparatus 709, a header decompressor 703 refers to reference information stored in a reference information manager 707 to decompress a compressed header of a packet received by a packet receiver 704. An error detector 702 detects a CRC error in the packet with its header decompressed by the packet receiver 704, and outputs only a correct packet. A successive error counter 705 counts the number of successive errors detected by the error detector 702. A successive decompression success counter 706 counts the number of decompression successes that successively appear. By referring to these counted numbers, an update request unit 708 transmits an update request to a transmitting side as required. A reference information manager 707 manages the reference information for header decompression. With this structure, the header decompression apparatus can request update of the reference information based on the state of the error.

Abstract: A cluster of genes involved in the synthesis and/or addition of oleandrose to avermectin aglycones has been cloned. A 11-kb <i>Pst</i>I clone complemented 28 avermectin glycosylation mutants in seven complementation classes.  Sequencing of an 10-kb region identified 9 ORFs and an additional partial ORF.  Eight of the ORFs were correlated to the seven glycosylation complementation classes. Sequence comparison to Genbank databases identified 6 genes: dTDP-glucose synthase; dTDP-glucose 4,6 dehydrase; dTDP-4-keto-hexose reductase;  dTDP-hexose 3,5 epimerase; dTDP-hexose 3' O-methylase; and an avermectin aglycone-dTDP-oleandrose glycosyltransferase.
